iris germanica symmetry

Symmetry in biology is the balanced distribution of duplicate body parts or shapes. In nature and biology, symmetry is approximate. For example, plant leaves, while considered symmetric, rarely match up exactly when folded in half. Symmetry creates a class of patterns in nature, where the near-repetition of the pattern element is by reflection or rotation. The body plans of most multicellular organisms exhibit some form of symmetry, whether radial symmetry, bilateral symmetry or "spherical symmetry". A small minority, notably the sponges, exhibit no symmetry (are asymmetric).

Iris germanica, the German Iris, is a species in the genus iris. The Iris Germanica grows up to 90 cm high and 10 cm wide. The roots can go up to 10 cm deep. It is an outdoors plant that blooms most in May-August, but planting it would be best in February-April.

Iris is an ambiguous color term, usually referring to shades ranging from blue-violet to violet.

However, in certain applications, it has been applied to an even wider array of colors, including pale blue, mauve, pink, and even yellow (the color of the inner part of the iris flower).

The name is derived from the iris flower, which comes in a broad spectrum of colors.

The first recorded use of iris as a color name in English was in the year 1916.
